DESCRIPTION
The 74V1G14 is an advancedhigh-speed CMOS
SINGLE SCHMITT INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiringC
2
MOStechnology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunityand stable output.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
S
(SOT23-5L)
C
(SC-70)
ORDERCODE:
74V1G14S 74V1G14C
regard to the supply voltage. This device can be
used to interface 5V to 3V.
Pin configuration and function are the same as
those of the V1G04 but the V1G14 has
hysteresis.
This together with its schmitt trigger function
allows it to be used on line receivers with slow
rise/fallinput signals.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
